Refer to the suggestion from my comment here: https://forum.plutonium.pw/topic/42294/game-wont-save-data-properly/2

@Xerxes I uninstalled the game, re-installed it and it actually opened in windowed mode. Other than that, no improvement

Does anyone know?

yes its fixed his version was outdated

Hi amigos I'm a player from Mexico so please excuse my english: ¡I got it! - in my case, it was fixed by installing the offline plutonium (.bat) from github, which asked me to unify the folders (I had bo2 multiplayer and zombies in two separate folders, so I just combined everything and replaced what needed to be replaced). Additionally, the offline plutonium patch asked me that the folders do not have dashes(-), spaces, uppercase letters, or characters that are not numbers, underscores(_), or lowercase letters. (im my case I had "Black ops II - Multiplayer" so I changed it to "bo2" xd)I don't know which of these three causes fixed the problem, but now when I play plutonium.exe (online) and close the game, it saves the progress (without the need for commands and changing settings like FOV or others).

what? how you solved it. i got this question too mate
